This week I got a call from one of my team mates (Nashaat Sorial) telling me that he is facing a problem with his Hyper-V cluster..
He is running 3 Hyper-V hosts with Windows 2008 R2 SP1 running multiple applications. One of the hosts keep failing and He can not Live migrate any VM to the other hosts until restart.
We went through all well known workarounds for such cases like
1- if you have AV please disable
2- Also check http://technet.microsoft.com/en-us/library/cc773533%28WS.10%29.aspx
3- Please if you have teaming..Break it and check again
4- Please check http://support.microsoft.com/kb/981618
5- Make sure that you enable the "file and printer sharing" as well as the "client for MS networks" on the heartbeat networks cards on all nodes. http://support.microsoft.com/kb/2008795
So we have to start reading more in the cluster logs. You can generate the cluster logs as per
http://blogs.msdn.com/b/clustering/archive/2008/09/24/8962934.aspx
We got some interesting data and errors in the logs just like:
In Win2008 the Physical Disk resource type private property that stores the disk signature change from "Signature" and it is now "DiskSignature" in Win2008. The lack of the DiskSignature property not being populated was resulting in the resource failing to come online
ERROR_CLUSTER_GROUP_MOVING(5908)’ because of ”Virtual Machine Configuration R-Web2003′ is owned by node 2, not 1.’
mm.. So it looks like something from the Hardware level. Searching HP blades errors come with more useful information
he HP Integrated Management Log shows ‘ASR Detected by System ROM‘ along with the following events in the System event log on an affected machine:
Event Type: Warning
Event Source: hpqilo2
Event Category: None
Event ID: 57
Failed GET SENSOR READING, sensor 16
Event Type: Warning
Event Source: hpqilo2
Event Category: None
Event ID: 57
NetFN 0x4, command 0x2D timed out
The solution for this was to perform the following:
- Install the latest ILO Firmware Update v. 1.81
- Install the HP iLO Management Channel Interface Driver v. 1.15.0.0
- Install the HP ProLiant iLO2 Management Controller Driver v. 1.12.0.0
All of these drivers can be downloaded form the following location, selecting your operating system:
